Perna, a treadmill is a great idea! I have one. I also have a bowflex, the excersise ball, hand weights, bands but I like my treadmill the best especially when the weather is cold. I go in my room, shut the door and put on some loud music and just walk. I don't time myself or worry about speed. Sometimes I find that I've walked through 2 cd's before I stop. I let my mind wander wherever it wants to. Not only is it good for the waistline but raising the endorphins is the best natural way to fight depression.

You can do it!
